Hvac fan and register system

ABSTRACT

A HVAC Fan and Register System is presented. The HVAC Fan and Register System has a vent housing forming a vent which can be inserted into an HVAC register. The fan is activated by the airflow produced when the HVA system is activated. The increase in airflow provides a faster method to accomplish the desired temperature. The fan being located in the HVAC register allows for a safe position. The fan may be permanent or removable. The fan may be steel, aluminum, wood, etc.

FIELD OF THE INVENTION

This invention relates to HVAC systems. More particularly, it relates to HVAC systems with a register and a fan.

BACKGROUND

A centralized forced air handling system represents the preferred choice and the most commonly installed type of system. The design of such a system and its installation provide a number of benefits for the heating and cooling of a structure, such as a residence. However, there are also certain shortcomings, principally air delivery and circulation problems associated with such centralized systems.

The air delivery and circulation problems are created by the use of a single, central blower to force the heated or air-conditioned air up through the network of air ducts to the various rooms and living spaces of the structure. The air duct paths differ from room to room in both their specific routing as well as their length or distance from the central blower.

Realizing that the forced air, whether heating or cooling, will not flow in a uniform and balanced fashion equally to every corner of every room, there exists the potential for certain rooms and spaces which are farther from the blower to receive inadequate air flow and as a result inadequate heating or cooling. Sometimes the various curves and bends of the air ducts contribute to the inadequate or insufficient air delivery. In other arrangements, it may simply be the distance from the central blower which is the primary contributor to inadequate air delivery.

Regardless of the specific reasons, when the air delivery to a particular room or space is not sufficient to provide adequate heating in the winter and cooling in the summer, there is a need to improve upon the system so as to correct this problem. Merely increasing the air delivery (volumetric flow) rate from the centralized blower is not the answer. As indicated, there are only certain rooms and spaces which are receiving an adequate air flow. There are typically other portions of the structure which are in a more direct line with the blower and/or at a shorter distance away from the blower which are adequately heated and cooled. In some instances, these areas might already be receiving too much air flow due to the difficulties in trying to balance out the heating and cooling in all corners of a large structure, such as a two story home. In order to solve the problem of certain rooms or spaces being too cold in the winter and too warm in the summer, some corrective measure needs to be taken on a room-by-room basis.

Associated with inadequate air flow is the air circulation reality that cooler air settles in the lower regions of a room or structure and that warmer air rises. When dealing with a two-story home, for example, this is another factor which influences whether all of the various rooms will be somewhat balanced as to their heating and cooling temperatures. As noted, since the central system relies on a single blower (air delivery device) to satisfy the air delivery requirements for all rooms, the chance for variations and inadequate air delivery to certain more remote rooms is relatively high.

In order to solve the aforementioned problem which is associated with conventional forced air handling systems, designs have been conceived to introduce a supplemental flow of air (fan-driven) between the main blower and the room or space which has an insufficient air flow. Typically, such designs are positioned near or in the air delivery duct which is associated with the particular room or space. Many of these supplemental designs are best described as fan-equipped air delivery devices and in certain arrangements are self-contained as a separate module.

There remain a number of shortcomings and drawbacks with each of these earlier inventions. For example, many of the earlier designs are fashioned on the theory of one-size fits all, without regard to the size of the room which is not getting adequate air flow. Other designs position the fan in a wide-open area without any enclosure or shroud, thereby allowing inefficient air flow patterns and the recirculation of “dirty” air back into the fan by way of any clearance around the outermost tips of the fan blades.

As to those earlier designs which provide only a constantly ON or OFF mode of operation, there is no ability to control when additional air flow should be provided based on the temperature within the room. As to those designs which mount externally to the existing vent, whether over or onto a wall or floor register, what results is a cumbersome device which interferes with the free movement into and out of the room and which restricts the positioning of furniture within the room.

As to those designs which are not modular or otherwise self-contained, the existing register must be removed and access provided to the interior of the air delivery duct. The additional attachment of various brackets and supports for positioning the fan in the duct must also be performed piece-by-piece and this results in a substantial inefficiency as to both cost and labor time.

DETAILED DESCRIPTION

Reference will now be made in detail to the present preferred embodiments, examples of which are illustrated in the accompanying drawings. All terms in the plural shall also be taken as singular and vice-versa. Further, any reference to he shall also be applicable to she and vice-versa.

Referring to FIG. 1, a view of a two-blade fan and floor air register where the air flows increases upwards is shown. The two-blade fan 100 has a flat side 102 and a rounded side 104. The air 106 being pushed towards the two-blade fan 100 on the flat side 102 increases the air pressure on the flat side 102 of the two-blade fan 100. When the high-pressure air contacts the flat side 102 of the two-blade fan 100, the air 108 increases and reduces the air pressure on the rounded side 108 of the two-blade fan 100.

Therefore, the floor vent 110 is placed on the air pipe to dispense either cold air or hot air into a room and to lower or raise the temperature of the room to a desired room temperature. The two-blade fan 100 is placed into the floor vent 110. The two-blade fan 100 is placed in such a way where the flat side 102 of the two-blade fan 100 is facing downward into the air source. The rounded side 104 of the two-blade fan 100 is placed upwards to increase the air speed into through the floor vent 110.

The air pressure is higher from the source of the air and the air 106 is directed to the floor vent 110 and contacting the flat side 106 of the two-blade fan 100. The air 106 causes pressure on the flat side 106 and causes the two-blade fan 100 to turn. The turning of the two-blade fan 100 causes the air pressure to fall and the air 108 speed to increase, thus pushing more hot or cold air into the room and either cooling or heating the air at a higher rate. Thus, the temperature of the room reaches the desired room temperature more quickly and allows the HVAC system to become idle and saving money while providing comfort more quickly.

Moving to FIG. 2, a view of a two-blade fan and ceiling air register where the air flows increases downward is shown. The two-blade fan 200 has a flat side 202 and a rounded side 204. The air 206 being pushed towards the two-blade fan 200 on the flat side 202 increases the air pressure on the flat side 202 of the two-blade fan 200. When the high-pressure air contacts the flat side 202 of the two-blade fan 200, the air 208 increases and reduces the air pressure on the rounded side 208 of the two-blade fan 200.

Therefore, the ceiling vent 210 is placed in the ceiling and attaches to the air source to dispense either cold air or hot air into a room and to lower or raise the temperature of the room to a desired room temperature. The two-blade fan 200 is placed into the ceiling vent 210. The two-blade fan 200 is placed in such a way where the flat side 202 of the two-blade fan 200 is facing upward into the air source. The rounded side 204 of the two-blade fan 200 is placed downwards to increase the air speed into through the ceiling vent 210.

The air pressure is higher from the source of the air and the air 206 is directed to the ceiling vent 210 and contacting the flat side 206 of the two-blade fan 200. The air 206 causes pressure on the flat side 206 and causes the two-blade fan 200 to turn. The turning of the two-blade fan 200 causes the air pressure to fall and the air 208 speed to increase, thus pushing more hot or cold air into the room and either cooling or heating the air at a higher rate. Thus, the temperature of the room reaches the desired room temperature more quickly and allows the HVAC system to become idle and saving money while providing comfort more quickly.

Now moving to FIG. 3, a view of a two-blade fan and wall air register where the air flows increases outward is shown. The two-blade fan 300 has a flat side 302 and a rounded side 304. The air 306 being pushed towards the two-blade fan 300 on the flat side 302 increases the air pressure on the flat side 302 of the two-blade fan 300. When the high-pressure air contacts the flat side 302 of the two-blade fan 300, the air 308 increases and reduces the air pressure on the rounded side 308 of the two-blade fan 300.

Therefore, the wall vent 310 is placed in the wall and attaches to the air source to dispense either cold air or hot air into a room and to lower or raise the temperature of the room to a desired room temperature. The two-blade fan 300 is placed into the wall vent 310. The two-blade fan 300 is placed in such a way where the flat side 302 of the two-blade fan 300 is facing toward the air source. The rounded side 304 of the two-blade fan 300 is placed outwards to increase the air speed into through the wall vent 310. The two views are dependent on whether the user decides to move the direction to a left or right area and may depend upon the location of the wall vent 310 and the desired direction of the air flow by the user.

The air pressure is higher from the source of the air and the air 306 is directed to the wall vent 310 and contacting the flat side 306 of the two-blade fan 300. The air 306 causes pressure on the flat side 306 and causes the two-blade fan 300 to turn. The turning of the two-blade fan 300 causes the air pressure to fall and the air 308 speed to increase, thus pushing more hot or cold air into the room and either cooling or heating the air at a higher rate. Thus, the temperature of the room reaches the desired room temperature more quickly and allows the HVAC system to become idle and saving money while providing comfort more quickly.

Referring now to FIG. 4, a flowchart showing the exemplary HVAC Fan and Register System, which may be referred to as an Aeroregister, is presented. At 400, the flowchart begins at start. The user selects the type of fan to insert into the air register 100. The type of fan may be a two-blade, four-blade, etc. The fan may be made of wood, metal, aluminum, etc. When the air register is a floor vent 110, the user inserts a fan 100 to increase the flow of air into the room in a upwards direction, when the air register is a ceiling vent 210, the fan 200 is inserted to direct the air flow into a downward direction, etc.

A desired temperature is set and the HVAC system starts up and pushes air to adjust the temperature of the air in the room to the desired temperature at 420. Once the HVAC system has activated, at 430, the air flow is pushed through the HVAC system and through the air register 110 into the room. At 440, the forced air 106 is pushed against the fan 100 and turns or rotates the fan 100 to increase the speed of the air 108.

At 450, the air flow increases and the room is heated or cooled to adjust the room temperature to the desired temperature. The HVAC system continues until the air temperature matches the desired temperature and at 460 the HVAC system shuts off and forced air from the HVAC system subsides, thus not creating an air pressure difference between the flat side 102 and the rounded side 104 of the fan 100.

At 460, the fan 100 comes to a halt and no further air is enhanced by the fan 100. The process stops at 480. When the HVAC system is reactivated, if the fan 100 has not been removed from the air register 110, then the process begins again at 400.
